Summary of the phylogenetic tree from ML analysis of rps16+trnS-G+trnL+trnL-F+ITS dataset showing the phylogenetic relationships within tribe Lithospermeae. Bootstrap support values and posterior probabilities are indicated above branches. Outgroups are indicated, Lithospermeae genera are colour coded.

Tribe Lithospermeae (Boraginaceae) consists of ca. 26 genera and 470 species, in which Onosma constitutes approximately one third of the species (~150). Although the tribe is strongly supported as monophyletic, both generic and species boundaries remain ambiguous. Among them, not only the phylogenetic position of Eastern Asian Onosma species, but a...

... genus Onosma and its subsections, namely, Onosma, Haplotricha and Heterotricha Riedl (1967) did not resulte monophyletic in any of the analyses (Table 3, Fig. 1) (Appendix 3-10). In contrast, Onosma s.s. was monophyletic (93-100% BS, 0.99-1.00 PP) in all analyses, except the plastid matrix analysis, where the clade was not ...

... Nasrollahi & al. (2019) reported a monophyletic position for Onosma hookeri and to date only one O. sinicum Diels sample was included in the previous studies (e.g., Chacón & al. 2019), the analyses of the current study showed that neither O. sinicum nor O. hookeri are monophyletic (Fig. 1). Indeed, misidentifications are common in Boraginales (Dr. Aslı Doğru Koca, pers. comm.) and the amount of wrong identifications in voucher specimens is reported to be very high in public molecular repositories (Nilsson & al. 2006;Wu & al. 2021). In the current study, I did not filter GenBank sequences by their reliable IDs or ...
